Researchers in the School of Anthropology examined social networks in the late pre-Hispanic Southwest and found that communities that were more connected with their neighbors had a better chance of being able to manage a crisis successfully than did communities with fewer outside connections. It is a finding that could have implications for crisis management research today.

"In a lot of modern research in crisis management, people are looking at how communities mobilize along social networks to overcome traumatic environmental crises, like we saw with Hurricane Katrina," says Lewis Borck, lead author of the study and a Ph.D. candidate in the College of Social and Behavioral Sciences.
